Direct browser-to-API processing
How to use Merge PDF
- Add between two and ten PDF files, each no larger than 25 MiB.
- Review the file list, remove anything you do not need, and arrange the PDFs in the desired order.
- Select Merge PDFs, wait for processing to finish, and download the combined PDF.
About Merge PDF
The merger appends complete PDFs sequentially, so the first selected document appears first in the result and no pages are silently selected or omitted. If you need only certain pages, extract them before merging.
Why use this tool
- Build one document from several PDFs.
- Control the sequence before processing.
- Download a standard PDF that is easier to share.
Privacy and security
Your selected PDFs are sent directly from your browser to api.choosifyapps.online for processing. They do not pass through WordPress and are not saved in its Media Library, posts, or uploads directory. API-side processing is temporary and follows the API’s configured behavior.
Frequently asked questions
How many PDFs can I merge at once?
You can merge between two and ten PDFs in one request. Each file can be up to 25 MiB.
Does the order of my files matter?
Yes. The output follows the order shown in the file list, so arrange the documents before starting the merge.
Can I merge only selected pages from each PDF?
This tool merges complete PDFs. Use Extract PDF Pages first when you need a smaller selection, then merge the resulting files.
Why was an encrypted or damaged PDF rejected?
The API must be able to read every input document. A corrupt, unsupported, or inaccessible encrypted PDF may not be processable.
